Impact de la chirurgie bariatrique sur le pronostic obstétrical

OBJECTIVES: Assessment of pregnancy outcomes after bariatric surgery and analysis of follow-up particularities of such pregnancies. PATIENTS AND METHODS: A retrospective study of 63 post-bariatric surgery pregnancies compared to 259 pregnancies of obese un-operated patients. Pregnancy outcomes, neonatal datas, delay influence between surgery and pregnancy beginning, bariatric surgery type and gastric banding (GB) loosening consequences were analysed. RESULTS: In the surgical brand were developed less gestational diabetes (DG) (P=0,05), deliveries were more often normal (P=0,004) and births shown less macrosomias and small for gestational age newborns (P=0,04). Neonatal state was improved among operated patients: less Apgar scores less than 7 at 1 minute (P=0,05) and less cord blood pH less than 7,2 (P=0,03). They gained more weight during the pregnancy (P=0,0003) and only 53% had a nutritional management and assessment. Patients with GB loosening gained more weight (P=0,0003). Lastly, there were no difference due to the different bariatric surgery techniques or nutritional follow-up in the pregnancy course and neonatal state. DISCUSSION AND CONCLUSION: Bariatric surgery improves obstetric and neonatal prognosis. Improvements have to be developed in the multidisciplinary follow-up in order to avoid nutritional deficiencies or important weight gain pregnancy in case of GB.
